The efficient removal of perfluorooctanoic acid (PFOA) is challenging, as conventional monometallic MOFs and powdered activated carbons suffer from limited active sites, poor stability, or unfavorable morphologies. Herein, a novel spherical porous carbon (SPC) derived from Cu/Zn-BTC bimetallic MOF was synthesized via glucose-assisted hydrothermal carbonization and high-temperature pyrolysis. Featuring high sphericity, uniform pore channels, and abundant bimetallic active sites, SPC exhibits enhanced PFOA adsorption performance and water stability. The optimized SPC (5-(Cu/Zn-BTC)) achieves a maximum adsorption capacity of 480 mg/g (surpassing most reported materials), with pseudo-second-order kinetics and spontaneous exothermic adsorption behavior. Synergistic mechanisms dominate the process: Cu2+/Zn2+-carboxylate coordination (XPS verified), acidic-condition electrostatic attraction (Zeta potential supported), and hydrophobic interactions. Notably, SPC retains high adsorption efficiency after five regeneration cycles due to robust structural stability. This work exhibits certain potential application value in the field of PFOA removal from aqueous systems.

The design of charge trapping sites is the basic and critical factor to explore the organic photomultiplier phototransistor and synaptic transistors. There are few examples of charge trapping directly by constructing dielectric materials, because the traditional view is that the band gap of dielectric materials is very wide for difficulty of the trap and release of charge. This work employs the Liquid Phase Epitaxy (LPE) method to construct two-dimensional confined dielectric MOF-199 island-like film with 20 nm diameter as the dielectric layer of bulk heterojunction based photo/synaptic transistors. Diverse energy level structures of metal complexes nanostructures integrated intrinsic charge trapping sites with multi-channel electron and energy exchange to active layer. The multi-channel exchange combines the response advantages of machines and the human brain, while the intrinsic charge trapping avoids interface charge quenching. It demonstrates simultaneous high photocurrent and well long-term plasticity, a high phototransistor performance of photo-responsivity R=650.1A·W-1/specific detectivity Dshot*= 6.76e15 Jones, and efficient photonic synaptic transistors with maximum paired pulse facilitation (PPF) index of 142%, single-pulse remaining ratio 65%. All these results point out the organic phototransistors for emulate the functions of biological synapses, which indicate its potential as the building block of bionic electronic circuits systems.

Efficient separation of dyes from salts in high-salinity dye wastewater remains a critical challenge, limited by the permeability–selectivity trade-off and fouling susceptibility inherent to conventional nanofiltration. Here, an innovative strategy integrating synergistic metal-MOF coordination with in-situ assisted etching is proposed to construct a defect-free, highly permeable MOF-based separation layer via a scalable one-step phase inversion process. By coordinating in-situ grown ZIF-8 in the casting solution with tannic acid (TA) introduced via the coagulation bath, a crosslinked network with a high MOF loading of up to 33 wt% is constructed. Free Zn 2+ presented in the casting solution act as dynamic repairing agents, effectively healing structural defects and enhancing membrane integrity through synergistic coordination. Simultaneously, TA etches ZIF-8 to create a hollow architecture, dramatically lowering transmembrane permeation resistance and enhancing surface hydrophilicity. The resulting membrane achieves exceptional broad-spectrum dye rejection, a remarkably high pure water flux of 127 L m −2 h −1 ·bar −1 , and outstanding dye/salt selectivity (e.g., methyl blue/Na 2 SO 4 selectivity up to 967), along with superior anti-fouling performance and operational stability. This work not only presents a feasible and scalable route to fabricating high-performance nanofiltration membranes through a “coordination-repair-etching” mechanism, but also opens new avenues for sustainable resource recovery from complex saline wastewater.

The design of low-smoke and low-toxicity epoxy resin (EP) composite materials remained a significant challenge. In this study, a multifunctional MOF-based flame retardant (TP-P-Co-MOF) was synthesized using ZIF-67 as the framework via a three-step modification process. TP-P-Co-MOF incorporated Schiff base-conjugated structures, Co P synergistic flame-retardant sites, and a porous architecture, while exhibiting excellent compatibility with EP. At a 4 wt% loading, the EP/TP-P-Co-MOF composite attained a UL-94 V-0 classification and an LOI of 31.3%. Additionally, in comparison with EP, the EP/TP-P-Co-MOF composite exhibited marked reductions in the peak heat release rate (PHRR), total heat release (THR), peak smoke production rate (PSPR), and total smoke production (TSP), which decreased by 43.1%, 14.9%, 64.0%, and 52.6%, respectively, thereby demonstrating outstanding flame-retardant efficiency and toxic-smoke suppression performance. Investigation of the flame-retardant mechanism indicated that TP-P-Co-MOF not only significantly improved the quality of the graphitized carbon layer in EP, but also reduces the concentration of combustible gases, thereby exerting synergistic flame-retardant effects in both the condensed and gas phases. With respect to mechanical properties, the incorporation of TP-P-Co-MOF improved both the toughness and strength of the EP. The tensile strength and impact strength increased by 11.1% and 24.7%, respectively, in comparison with neat EP. This study provided a promising strategy for developing highly efficient MOF flame retardants while offering a novel approach to designing low-smoke, low-toxicity flame-retardant EP.

Developing efficient bifunctional electrocatalysts capable of facilitating water splitting to produce hydrogen and oxygen remains a significant challenge. This study presents a controllable conversion of MOFs to carbon-coated NiCoP nanostructures via low-temperature phosphidation using a NiCo-MOF/Ti 3 C 2 T x precursor, leading to the construction of the NiCoP@C/Ti 3 C 2 T x bifunctional electrocatalyst. Characterization of the synthesized NiCoP@C/Ti 3 C 2 T x composite material and electrochemical testing revealed that the material exhibits high catalytic activity in both HER and OER. At a current density of 10 mA cm −2 , the overpotential for HER is measured at 58 mV with a Tafel slope of 60 mV dec −1 , while the overpotential for OER is found to be 240 mV, with a Tafel slope of 42 mV dec −1 . The potential required to achieve a current density of 10 mA cm −2 for overall water splitting is 1.53 V, which is lower than commercial Pt/C and RuO 2 electrocatalysts. Additionally, the material demonstrates excellent electrocatalytic performance at higher current densities. The outstanding electrocatalytic performance is attributed to the effective stabilizing effect of the carbon-coated layer on the high-activity NiCoP particles, thereby suppressing the loss of active sites during the reaction. Moreover, the strong interfacial coupling effect between NiCoP and Ti 3 C 2 T x significantly enhances the interfacial charge transfer kinetics, consequently improving catalytic efficiency.

Lithium-sulfur batteries (LSBs) are regarded as potential candidates for next-generation energy storage technologies, however, their practical applications are limited by the dual constraints of shuttle effect of lithium polysulfides (LiPSs) and slow catalytic reaction kinetics. To address these issues, a metal-organic framework (MOF)-derived composite Co 2 Mo 3 O 8 -MoO 2 heterojunction (Mo-Co@C) loaded on carbon nanorod clusters was designed. The heterojunction showed a low d -band center level and higher d -band density of state (DOS), and the inside built-in electric field can significantly enhance the adsorption of LiPSs and effectively inhibit the occurrence of the shuttle effect. In addition, the nanorod-like cluster formed by the self-assembly process of bimetallic organic framework exhibits a high specific surface area, which not only provided more active centers, but also the transport channel for lithium ions migration, and promoted the enhancement of the redox reaction kinetics simultaneously. The battery with the Mo-Co@C composites as a separator-mediator exhibited initial discharge capacity of 895.7 mAh g −1 at 1 C, and it still maintains a reversible capacity of 402.4 mAh g −1 after 1000 cycles, which corresponds to a capacity degradation rate of 0.055% per cycle. The capacity can still reach 501.3 mAh g −1 at 0.5 C even at a low-temperature of −20 °C. This work provides new insights for the design of catalysts for high-performance lithium-sulfur batteries.

Abstract Metal−organic framework (MOF)-based nanozymes have emerged as promising alternatives to natural enzymes for catalytic sensing due to their tunable porous architectures and abundant active sites. Nevertheless, the practical implementation of pristine Co-MOF nanozymes is severely hindered by intrinsic catalytic activity attenuation, poor structural stability, and unavoidable aggregation issues. In this work, a triple synergistic interface engineering strategy is proposed to fabricate high-performance and recyclable composite nanozymes via Prussian blue (PB) modification, polyvinyl alcohol (PVA) aerogel immobilization, and DNAzyme functionalization. The introduction of PB with self-amplifying catalytic behavior effectively optimizes the redox reaction kinetics of the Co-MOF, significantly boosting its peroxidase-like catalytic activity and structural durability. The three-dimensional porous PVA aerogel serves as a versatile supporting matrix, which not only uniformly disperses PB-modified Co-MOF nanocomposites to eliminate particle aggregation and catalyst waste but also endows the composite with excellent recoverability and cyclic usability. Furthermore, the integration of the hemin/G-quadruplex DNAzyme constructs a multilevel catalytic interface, which synergistically enhances the catalytic efficiency and environmental adaptability of the aerogel-based nanozyme system. Benefiting from the structural superiority and multi-component synergistic catalysis, the optimized DNAzyme@PB/Co-MOF PVA aerogel sensing platform achieves sensitive, stable, and visual detection of the total antioxidant capacity. This work systematically explores the mechanisms of multi-scale composite nanozymes, providing a feasible and universal strategy for the rational design and fabrication of high-stability, high-efficiency, and recyclable MOF-based functional catalytic materials for advanced sensing applications.

To develop a high-performance humidity sensor, MOF-303, possessing both micro- and mesoporous structures, was selected as the host material for the sensor. SnO 2 nanoparticles were introduced via wet impregnation, and Cu(II) ions were anchored onto uncoordinated nitrogen sites of MOF-303, forming a ternary Cu(II)/SnO 2 /MOF-303 nanocomposites. The optimal sample denoted as 1-2CuSnM (with a molar ratio of Cu(II) to SnO 2 /MOF-303 of 1:2) achieved a response value of 116.98 over 11-98% RH, with response/recovery times of 16.2/6.3 s, low hysteresis (2.48% RH), and excellent 30-day stability (SD < 0.01) at room temperature. The synergy between Cu(II) and SnO 2 introduces abundant oxygen vacancies for water adsorption, while uncoordinated N sites enable proton hopping (Grotthuss mechanism) and Cu(II) dissociation enhances ionic conductivity, collectively reducing impedance. This ternary strategy is novel in combining protonic and ionic conduction pathways within a MOF framework, enabling a humidity sensor with wide range, fast response, and low hysteresis, key advancements over conventional materials.

A heterojunction with g-C 3 N 4 @Zn/Eu-MOF covalent interface was synthesized. • g-CN@MOF can be used for photocatalytic degradation and fluorescence detection of ofloxacin. • Efficient removal of ofloxacin in milk by g-CN@MOF foam. • g-CN@MOF can detect ofloxacin residues in milk through smartphone-assisted color recognition. Ofloxacin (OFL) is widely used in medicine and animal husbandry, and its residues in milk raise substantial food-safety concerns. Herein, a dual-functional covalently coupled g-C 3 N 4 @Zn/Eu-MOF composite (g-CN@MOF) was constructed through a one-pot hydrothermal route. FTIR and XPS analyses indicated the formation of C N C O linkages between g-C 3 N 4 and the MOF, yielding an interfacially coupled type-II heterojunction that promoted charge separation. The optimized g-CN@MOF-30 achieved 69.21% removal of 10 mg L −1 OFL within 120 min under visible light, with •O 2 − and •OH identified as the dominant reactive species. Meanwhile, the fluorescence intensity ratio F 440 /F 595 showed a linear response to OFL over the range of 0–100 μM, affording a detection limit of 0.011 μM through an IFE-dominated ratiometric sensing mechanism. After immobilization in sodium alginate foam, the composite exhibited convenient recyclability and enabled OFL removal from pretreated milk samples, while smartphone-based RGB analysis provided rapid visual semi-quantification with recoveries ranging from 100.3% to 109.9%.

Underwater plasma enables one-step PFAA degradation and F-doped CoFe 0.5 BDC synthesis. • F-doping optimizes electron transfer and enhance adsorption of *OH intermediates. • F-doping unlocks lattice oxygen activation at the Fe/Co dual sites. • The LOM-driven OER pathway significantly lowers the reaction barrier. Electrocatalytic water splitting faces efficiency challenges due to sluggish oxygen evolution reaction (OER) kinetics. Here, we develop an underwater spark plasma discharge strategy to simultaneously degrade perfluoroalkyl acids (PFAAs) and synthesize F-doped CoFe 0.5 BDC electrocatalysts using recovered fluorine. The resulting F 7 -CoFe 0.5 BDC (derived from heptafluorobutyric acid) exhibits exceptional OER performance in alkaline media, achieving a low overpotential of 271 mV at 10 mA cm −2 with robust stability. In-situ characterization and density functional theory (DFT) calculations reveal that F-doping activates the lattice oxygen mechanism (LOM) by optimizing electron transfer and enhancing adsorption of *OH intermediates at Fe/Co dual sites. This work integrates pollutant degradation with circular catalyst fabrication, establishing a sustainable paradigm for designing high-performance OER electrocatalysts via lattice oxygen activation. A sustainable “pollutant-to-catalyst” upcycling strategy is developed via an underwater spark plasma method, which enables simultaneous perfluorinated pollutant degradation and the in-situ synthesis of F-doped CoFe-BDC. The incorporated F atoms activate the lattice oxygen mechanism on adjacent Fe/Co dual sites, significantly lowering the OER energy barrier. This work provides a green, generalizable pathway to design high-performance electrocatalysts from environmental waste streams.

A PEDOT-MOF/polypeptide modified multi-modal micro-ECoG electrode is proposed. • PEDOT-MOF achieves dual functions of ROS sensing and efficient scavenging. • Polypeptide/DEX enhances electrode biocompatibility and reduces inflammation. • In vivo validation of multi-modal ECoG/ROS recording and immunomodulation The limited biocompatibility of conventional flexible electrode materials often triggers host immune responses, manifesting as glial encapsulation and the overproduction of reactive oxygen species (ROS). Meanwhile, ROS accumulation further exacerbates local inflammation and induces irreversible cellular damage. Therefore, constructing a highly biocompatible electrode-tissue interface and developing multi-modal microelectrodes capable of recording and regulating in-vivo ROS concentrations are critical for alleviating immune responses and clarifying the underlying mechanisms of electrode failure. In this work, we proposed a novel modification strategy for micro-electrocorticography (micro-ECoG) electrodes to enable multi-modal neural recordings (ECoG and ROS) and regulations (drug deliver and ROS catalyze). For this purpose, the electrode surface is modified with Cu-metal-organic framework (Cu-MOF)-doped poly(3,4-ethylenedioxythiophene): polystyrenesulfonate (PEDOT:PSS), denoted as PEDOT-MOF. Additionally, a highly biocompatible polypeptide coating loaded with anti-inflammatory drugs is introduced to further suppress immune reactions. In vitro experiments reveal that PEDOT-MOF exhibits excellent electrochemical performance and detection sensitivity to H₂O₂, indicating its multifunctionality to catalyze the ROS for mitigating oxidative stress and monitor dynamic changes in ROS concentration in real time. In vivo implantation studies confirm that microelectrodes modified with the drug-loaded polypeptide coating exhibit lower interface impedance and higher SNR. Collectively, these results highlight the significant application potential of PEDOT-MOF-modified micro-ECoG electrodes combined with a drug-loaded polypeptide coating, which may address key challenges in current implantable neural electrode technology. It should be noted that, due to partial channel attenuation over chronic implantation and spatial diffusion effects of dexamethasone, this platform is more suited for monitoring relative ROS dynamic trends. Future optimizations will further advance the capability toward accurate in-vivo ROS absolute quantification.

GOx@ZIF-90@CuCo-MOF composite was synthesized via synergistic self-assembly. • Bimetallic sites and ZIF-90 shell significantly enhanced nanozyme activity. • The GOx@ZIF-90@CuCo-MOF paper-based nanozyme sensor was fabricated for rapid and noninvasive glucose detection in saliva. • The sensor achieved a 13.5 μM detection limit within a 20-min reaction. Glucose biosensors are pivotal to diabetes management; however, traditional fingerstick blood collection methods are often challenging due to their invasiveness, pain, high cost, and inability to provide continuous monitoring. Here, we constructed a paper-based colorimetric sensing platform using a multifunctional metal–organic framework (MOF) composite system to enable rapid, noninvasive detection of glucose in saliva. This platform utilized a CuCo-MOF framework, loaded with glucose oxidase (GOx) and ZIF-90 via a synergistic self-assembly mechanism, to catalyze the colorimetric reaction of H 2 O 2 and tetramethylbenzidine (TMB). The synergistic effect of the composite significantly enhanced the overall catalytic efficiency, enabling a sensitive response to glucose levels in saliva. Using ImageJ, color images captured with a smartphone were analyzed using RGB color channels to quantitatively determine glucose levels in saliva. The detection time was 20 min, with a detection limit (LOD) of 13.5 μM and a linear range of 50–2000 μM. This platform offered advantages with the absence of blood sample collection, ease of operation, and visual response. It provided new material strategies and design ideas for developing portable, non-invasive blood glucose monitoring technology.
